LUD HOLLAND-LETZ, OF OAK PARK, ILLINOIS, ASSIGNOR TO INTERNATIONAL HAR-VESTER COMPANY. OF NEW J ERSEY, A CORPORATION OF NEW JERSEY.A l

GRAIN-LIFTER FOR HARVESTERS.

Specification of Letters Patent.

Patented Nov. 14, 1916.I

Application led October 27, 1913. Serial No. 797,437.

To all 'whom t may concern Be it knownthat I, LUD HOLLAND-LETZ, acitizen of the United States, residing at Oak Park, in the county ofCook and State of Illinois, have invented certain new and usefulImprovements in Grain- Lifters for Harvesters, of which the following isa full, clear, and exact speciication. a

My invention relates to grain liftersfor harvesters, mowers or the like.

It has among its objects to provide an improved form of grain lifterwhich may be readily attached to or detached from the guards upon afinger bar, which is free to rise and fall at its front end to a limitedeX- tent in passing over uneven ground, and is adaptedto be attached tocutting apparatus having varying dimensions and forms.

A further object of my invention is to provide an improved grain lifterof simple, rugged and efficient construction which may be practicallyuniversal in its application and whichmay be manufactured at small eX-pense.

Other objects and-advantages of my 1mproved construction willhereinafter appear. Y

I attain these objects by means of an imf proved construction kof grainlifter adapted to be operatively connected to a nger bar insan improvedmanner, as hereinafter more .fully set forth.

In the accompanying drawings I havel illustrated oneembodiment which myinvention may assume in practice.

In these drawings: Figure 1 is a side elevation of a complete grainlifter attached to the finger bar of-a harvester and having my inventionembodied in its construction; Fig. 2 isa top plan view ot' part of Fig.1 on-an enlarged scale; Fig. 3 is a detached detail viewv of a part ofFig. 2; Fig. 4 is a sectional side elevation of the device when in thenormal operative position; Fig. 5 is a View similar to Fig. 4, showingthe lifter raised at its front end to pass an obstruction; and` Fig. 6is a cross section of Fig. 4 along line A-B.

The same reference characters designate like parts throughout theseveral views.

1 represents the finger bar of a harvester or other machine, 2 is aguard finger secured thereto by means of a bolt 3, 4 a longitudinallygrooved trunnion-receiving member that-ie secured te the .upper side Aofthe finger bar by means of the same bolt, and 5 representsV a'bracketmember having a box-like form and provided with inwardly turnedtrunnions 6 at its rear end thaty are received by the saddle member 4ina manner to permit the bracket member to swing in a vertical plane, thebracket being secured to the saddle by means of washers 7 upon the bolt3. y

'8y represents a bar, preferably of channel shape and forming the bodyof the lifter, and havingv its rear end secured to the front end of thebracket 5 by means lof rivets 9.

10 represents a rod secured to the front end of the bar and disposedupwardly and rearwardly and operating as a lifter for fallen grain, therodbeing of such dimensions as will permit it to yield under heavy duty.n v

11 represents aguard-engaging or holding member of tubular formfhavingits rear end partially inclosed and adapted to receive the point of theguard, its front end being provided with a cross head 12 and arearwardly extending centrally disposed rib 13 that is received by alongitudinally disposed slot 14 in the body of the bar 8, whereby theholding member may move along the bar to accommodateitself to variouslengths of guards, the slot at its front end being widened to permit thecross head to pass through. As shown, the cross head 12 secures themember 11 in operative position when" it is moved along the slot, andthe rib 13 is wide enough to prevent the holding member from swinginglaterally.

15 represents a curved swinging and bodily movable lifter controllingbell crank lever having a narrow body portion that is slid'ably receivedby a slot 16 disposed longitudinally in the bar 8 and provided at oneend with laterally disposed trunnion members- 17 that are received bytrunnion receiving members 18 `formed upon the rear end of the holdingmember 11, said lever at its opposite end being provided :with a crosshead 19 that contacts with. the side walls of being sperative tonormally bold the bar S in its lower relative position, as shown in Fig.Obviously when the bar meets an obstruction it will rise against thetension Y of the spring, as shown in Fig. 5, until the cross head 19,which then engages the spring 2O moves along the slot 16 and toward thefront end thereof into a neutral position, as

shown in Fig. 5, and when the bar S has cleared the obstruction thespring 2O autoinaticallv returns it to its normal operative position.

The lifter mechanism, as illustrated and described, automaticallvadjusts itself however, that the embodiment shown hereinv for purposesor illustration may be modified without departing from the spirit of myinvention as disclosed in the appended claims.

N hat I claim as my invention, and desire to secure by Letters Patent,is:

l. In a grain lifter, va slotted supporting bar, and a guard-engagingmemberinovable in said slot and having a shoulder resting on one of theedges thereof.

2. In a grain lifter, a slotted supporting bar, and a guard-enga gingmember movable in said slot and having oppositely disposed shouldersresting on the opposite edge thereof.

3. In a grain lifter, a supporting member having a slot therein providedwith an enlarged opening communicating therewith, and a guard-engagingmember y carried in said slot having a projection thereon removablebodily through said enlarged opening.

4L. In a grain lifter, a supporting member having a slot thereinkprovided with an enlarged opening communicating therewith, and aguard-engaging member carried in said slot having a cross head thereonremovable bodily through said enlarged opening.

5. In a grain lifter, a supporting member' having a slot Ythereinprovided with an enlarged opening communicating therewith, aguard-engaging member carried in said slot and having a cross headthereon re- Vmovable bodily through said enlarged opening, saidmemberbeing movable in a vertical plane in said slot.

6; In a. grain lifter, a slotted supporting "bar, a guard-engagingmember pivotally mounted thereon, a lever operatively connected to saidguard-engaging member and extending through the slot in said 'supportingmember, and resilient means controlling the movement of said. lever.
